ÏM = standard error of the mean Ï = the standard deviation of the original distribution N = the sample size âN = Root of the sample size. The standard error of the mean, also called the standard deviation of the mean, is a method used to estimate the standard deviation of a sampling distribution.To understand this, first we need to understand why a sampling distribution is required.

Acidosis and alkalosis describe the abnormal conditions that result from an imbalance in the pH of the blood caused by an excess of acid or alkali (base).
Respiratory alkalosis is a primary decrease in Pco2 with or without compensatory decrease in bicarbonate (HCO3â); pH may be high or near normal. Cause is an increase in respiratory rate or volume (hyperventilation) or both. Respiratory alkalosis can be acute or chronic. The chronic form is asymptomatic, but the acute form causes light-headedness, confusion, paresthesias, cramps, and syncope. Signs include hyperpnea or tachypnea and carpopedal spasms.
